TeleVue 90 Degree Everbrite Diagonal - 2 Inch

Tele Vue 90 Degree Everbrite Diagonal - 2 InchWhiter and brighter images. Simply put that is the benefit the Everbrite mirror coating. This exotic dielectric nonmetallic coating is 99% reflective across the full visual spectrum resulting in the "whitest" most natural image available. The coating is painstakingly applied to Pyrex with a surface accuracy of a 1/10 wave flatness. The Everbrite is offered in both 1¼" and 2" models. The diagonal bodies of each are machined from solid blocks of aluminum. In this way we can insure permanent alignment. The one piece body construction also assures heavy accessories can't force the diagonal body to "unscrew" from the barrel as with other brands. Both the 1¼" and 2" models feature brass clamp rings anti-reflection threads and 1¼" and 48mm filter threads respectively.
